My computer never shutdown  

This problem will happen on the computers that supports Advanced Power Management. By default, this feature will have been disabled in Windows XP. If the BIOS on your computer is set for APM, and if you have installed Windows XP then you we will get the message of shutting down and then it will be idle.Nothing will happen and will start to hang.The system will not respond. To avoid this you have to make changes in the power management. To do this follow the steps:

1.Enter into the control panel by clicking the start menu.

2.You will find the option "Performance and maintenance" there.

3.Here we will be having the option "Power Options"

4.Here Check the box to select the' Enable Advanced Power Management Support"

5.Click OK.

The above window may vary slightly in some systems depending on the configuration. But this is the procedure for most of the systems. You may try for that.

One cause of this is the persistent saving of a failed write on a storage media. Most probably the storage media has error or it is no longer available like a shared network drive or a removable drive. I believe ccleaner can fix the registry for this error, and a chkdsk for HDD access error. You can also try to shudown using a different account say Guest acount and see if its the same.

How about a full format on your computer if that still happen it would be a hardware problem them. Try to contact the dell support system if there is any instances that happen already to a same unit. I think the best would be try to reformat it and be sure to backup all files.
